Frequently asked questions and errors¶

From our years of experience in support, in most cases problems are solved by rechecking the prerequisites and then restarting the service. If not, perhaps this page can answer your problem, before writing to Scan support.

On the installation side¶

If the following message appears, please check prerequisites, in particular configured user rights to start the service.

The interface¶

Authentication problem¶

After logging on to the Scan FME interface, the scan interface may not be displayed. This is a problem that can occur when authenticating to Isogeo multiple times in different tabs.

To solve the problem, click on https://scan.isogeo.com/api/logout and try again.

Unable to access specified path¶

If one of the messages below is displayed, there is a problem with the access parameters for data entered in the entry point: path, schema, database, user rights...

¶

The service connects and disconnects continuously¶

Check that the user configured to launch the service has write access to the Isogeo Worker installation directory. If this is not the case, you need to give them this right and restart the service, then reload the interface to check that they don't log out again.

Known special cases¶

Shapefile greater than 2 GB¶

FME does not read shapefiles where the size of each component (.shp / .dbf / .shx ...) exceeds 2 GB, as indicated in the official knowledge base:

This is an inherent limitation of the format, which Esri explains in this article.

Service refuses to start (internal command not recognized)¶

Report¶

Problem¶

The problem stems from an inability to resolve the Windows path with spaces when it's the D drive (whereas it works on the C: drive).

Solution¶

Make sure there are no spaces or special characters in the path to the Scan service installation folder.
